    I am a freelance software engineer specializing in mobile app and full-stack software development. I have over 20 years of experience in professional software engineering. The last seven years of that has been working on web and mobile apps, their backends, cloud infrastructure, and devops. I am available for short-term freelance software engineering contracts in web full-stack, mobile app, and cloud infrastructure development, using Swift, Kotlin, React, TypeScript, JavaScript, Python, Java, Erlang, OCaml, Objective-C, and C. I work on multiple platforms including Docker, Amazon Web Services, Google Cloud, Linux and macOS. I have used many database backends, including ElasticSearch, MySQL, and PostgreSQL. I strongly prefer remote contracts, though I am open to work in the San Francisco area. Before freelancing I was the chief architect and founder at Tipbit, an email, calendar, and contacts app for iPhone and iPad. I have previously held roles as architect and director for XenServer at XenSource and Citrix, and founding engineer and technical board member for OpenStack. In general I have been a software engineer in telco, virtualization and cloud since 1997. I am a UK and US dual citizen. I have a degree in Computer Science from the University of Cambridge.

    For the last decade I’ve worked as a Senior Mobile and Full Stack Software Engineer in Silicon Valley. Some notable experience is my work for Apple on the iOS Photos app, and my work for Coinbase on their self custody Wallet app. From small startups to fortune 500 companies, brand new projects to apps with hundreds of millions of users, I’ve worked with all kinds of teams and software. While mobile app development is my strongest skill, I have lots of experience in full stack environments with a myriad of technologies and platforms. I also have quite a bit of experience with UI/UX, 3D Modeling, and even some firmware development. And while I do have many skills, I will be upfront about any technologies in which I don’t have past experience. I work efficiently and independently and I strive to deliver a value that more than exceeds my cost to clients. I’m passionate about high quality software and I look forward to working with your team to deliver just that!
